Research progress in nano-scaffolds for spinal cord tissue engineering / 国际生物医学工程杂志

ABSTRACT

Spinal cord injury is a difficult medical problem and need to be solved urgently.Application of tissue engineering to repair spinal cord injury has gradually become a hot spot.It is important to prevent the development of scar tissue while inducing cells' regeneration by using scaffold.Nanotechnology has improved the performance of scaffold because of its superiority.Nanoscaffold has obvious advantages compared with the traditional scaffolds.New scaffold materials can be obtained by nanotechnology.Nanoscaffold can also serve as a good drug carrier,and it may have beneficial effects on biological behaviors of seed cells on its surface,such as differentiation,proliferation and migration,which may promote tissue regeneration and functional recovery and get good results in repairment of spinal cord injury.This article summarized the research progress in recent years in nano spinal cord engineering scaffolds in order to provide a reference for research in related fields.
